posted on 03.07.2009, 13:02 authored by Tony Wynn, John H. RichardsonThe aim of this study was to establish subjective workload ratings (NASA-TLX)
for the ADAM surrogate reference task (SURT) and compare them to ratings of a test
battery of real IVIS tasks while participants performed a surrogate of the driving task (Lane
Change Task). The results indicated that subjective workload ratings were comparable for
both the real and reference tasks, performance measures were significantly correlated
with measures of subjective workload and that performance of the secondary reference
task declined as task difficulty increased. Reasons for the pattern of results are discussed.
